DESCRIPTION OF VARIOUS EMBODIMENTS

The following detailed description is to be read with reference to the drawings, in which like elements in different drawings have like reference numerals. The drawings, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of the invention. Skilled artisans will recognize that the examples provided herein have many useful alternatives that fall within the scope of the invention.

Referring to the drawings, and in particular, FIG. 1, there is shown an apparatus of the present disclosure generally represented by reference numeral 10. The illustrated apparatus 10 is a wake shaping apparatus, which preferably is configured to attach removably to a hull 40 of a boat 50. The wake shaping apparatus 10 is configured to disrupt water flow around the hull 40 such that a wake created behind the boat 50 during operation of the boat 50 is larger, differently positioned, and/or differently shaped than when the boat 50 is operated without the apparatus 10 attached to the hull 40.

As shown in FIG. 7, the apparatus 10 generally comprises a base 100 and a blade 300. The apparatus 10 has a first configuration 20 in which the blade 300 is mounted to the base 100, and a second configuration 30 in which the blade 300 is separated from the base 100. As described in greater detail below, in some embodiments, the apparatus 10 is configured to provide tool-free adjustment between the first 20 and second 30 configurations.

The base 100 generally has first 115 and second 120 end regions, and first 125 and second 130 side regions. The illustrated first 125 and second 130 side regions extend between the first 115 and second 120 end regions. The first end region 115 includes a front end 135 (see FIG. 3) of the base 100, and the second end region 120 includes a rear end 140 of the base 100.

The base 100 also has a top side 145 and a bottom side 148 (see FIG. 16). The top side 145 is opposite the bottom side 148. Preferably, the bottom side 148 is on the same side of the base 100 as one or more suction cups 105. When the apparatus 10 is attached to the hull 40 of a boat 50, the bottom side 148 faces (and is carried alongside) the hull 40, and the top side 145 faces away from the hull 40.

Referring to FIG. 8, the blade 300 has opposed first 305 and second 310 faces. In some embodiments, the first 305 and second faces 310 are identical, whereas in other embodiments, they are different. For example, the first face 305 of the blade 300 can have different structural features provided thereon and/or a different shape than the second face 310 of the blade 300. Such differences can optionally be provided to create different effects on the wake. In certain embodiments, one of the faces 305, 310 is convex (FIG. 12) and the other of the faces 305, 310 is concave (FIG. 13). However, in other embodiments, both faces 305, 310 of the blade 300 are planar. Alternatively, one face 305, 310 can be planar while the other face 305, 310 is either concave or convex.

As discussed above, the illustrated apparatus 10 has a first configuration 20 (see FIG. 7) in which the blade 300 is mounted to the base 100. When the apparatus 10 is in the first configuration 20, the blade 300 is in either a first orientation or a second orientation. The first face 305 of the blade 300 faces a desired direction relative to the base 300 when the apparatus 10 is in the first orientation. In contrast, the second face 310 of the blade 300 faces the desired direction relative to the base when the apparatus 10 is in the second orientation. It may be advantageous to change the blade 300 between the first orientation and the second orientation when the first 305 and second 310 faces of the blade 300 have different structures and/or shapes in order to achieve different effects on the wake.

The illustrated blade 300 has a mount structure 340 configured to attach to the base 100. The mount structure 340 preferably projects outwardly from the blade 300 (e.g., outwardly from a primary wall portion of the blade). For example, the mount structure 340 can optionally project outwardly from at least one, and preferably both, of the first 305 and second 310 faces of the blade 300. In some alternate embodiments, the base 100 is integral to (or permanently affixed to) the blade 300. However, in preferred embodiments, the base 100 and the blade 300 are configured to be attached to each other removably. Where the mount structure 340 projects outwardly from both faces 305, 310 of the blade 300, the blade 300 is configured to be removably attached to the base 100 in either of two orientations, i.e., in either the first or second orientation so that a desired one of the faces 305, 310 of the blade 300 faces the desired direction.

Preferably, the apparatus 10 is configured to be adhered to the hull 40 of the boat 50 by at least one suction cup 105 so as to removably attach the apparatus 10 to the hull 40 of the boat 50. However, the apparatus 10 can alternatively be removably attached to the hull 40 through other non-invasive forms of mechanical attachment, such as hook and loop fasteners, clasps, magnets, or the like. The removable nature of the apparatus 10 allows it to be used on a boat 50 that already has a built-in wake-shaping device so as to complement the effects provided by the built-in wake-shaping device. Alternatively, the apparatus 10 can be used on a boat 50 that does not have any other wake-shaping devices.

Thus, the apparatus 10 preferably can be attached removably to the boat 50 in a desired orientation and on a desired region of the boat 50. Both the orientation of the apparatus 10 when attached to the boat, and the region of the boat to which the apparatus 10 is attached, can be selected to achieve particular effects on the wake. For example, in FIGS. 1 and 3, the apparatus 10 is attached to the hull 40 of the boat 50 such that the front end 135 of the base 100 faces rearwardly of the boat 50. FIGS. 2 and 4 show the reverse orientation, i.e., the rear end 140 of the base 100 faces rearwardly of the boat 50. The apparatus 10 can be attached to the hull 40 of the boat 50 at a position that is adjacent to a stern 90 (FIGS. 1-4) or adjacent to a bow 95 (FIG. 5) of the boat 50. Additionally or alternatively, a wake shaping apparatus 10 can be attached to a bottom (or underside) 40U of the hull 40. Reference is made to FIG. 45. Any embodiment of a wake shaping apparatus 10 described in this disclosure can optionally be attached releasably to the bottom 40U of the hull 40. This can optionally be in addition to there being one or more wake shaping apparatuses provided on other locations of the hull. Alternatively, the only wake shaping apparatus 10 attached releasably to the hull may be on the bottom (or underside) 40U of the hull 40. This can optionally be the case in FIG. 45. While FIG. 45 shows the wake shaping apparatus 10 as being an inflatable apparatus 10 b, this is by no means required. To the contrary, FIG. 45 represents a group of embodiments wherein any wake shaping apparatus is attached releasably to the bottom (or underside) of a hull of a boat. In FIG. 45, the illustrated wake shaping apparatus 10 is attached to the bottom of the hull by a plurality of suction cups. However, various other releasable attachment means can be used instead.

In some embodiments, two wake shaping apparatuses 10 are each attached to the same side of a hull 40 of a boat 50. As shown in FIG. 6, one of the apparatuses 10 can be positioned adjacent to the bow 95 of the boat 50, while the other apparatus 10 is positioned adjacent to the stern 90 of the boat 50. Given the present teaching as a guide, skilled artisans will appreciate that the one or more apparatuses 10 can be mounted removably at various locations on the hull.

Tool-Free Adjustment

In certain embodiments, the base 100 and the blade 300 can be separated from each other to achieve the second configuration 30 described above. One example of the second configuration 30 is shown in FIG. 9. Preferably, when the apparatus 10 is in the second configuration 30, the base 100 and the blade 300 can be nested alongside each other so as to occupy a more compact (i.e., smaller) space than when the apparatus 10 is in the first configuration 40. In certain embodiments, the apparatus 10 when in the second configuration can have its blade and base nested alongside each other so as to fit within a rectangular volume (e.g., inside a box) having the following dimensions: 15 inches by 6 inches by 9 inches, or even 14 inches by 5 inches by 8 inches. While not in use, the apparatus 20 can be removed from the hull 40 of the boat 50 and stored conveniently until needed.

In some embodiments, the apparatus 10 can be adjusted from the first configuration 20 to the second configuration 30, and from the second configuration 30 to the first configuration 20, without using any tools, and preferably without removing or inserting any fastener from or into the base 100. In such cases, the blade 300 can be mounted to the base 100 and later removed therefrom without using any tools. This is particularly advantageous since the apparatus 10 is intended to be attached to the hull of a boat 50 at a location that is under water while the boat 50 is in operation. Using tools underwater can prove difficult due to visibility issues, the tendency of tools to become slippery when wet, and/or the potential for the water to be cold. These factors may lead to tools and/or fasteners being dropped into the water.

In some embodiments, an optional hook and loop fastener is sandwiched between the blade 300 and the base 100 when the apparatus 10 is in the first configuration 20. In such embodiments, the hook and loop fastener is configured to removably fasten the blade 300 to the base 100. When provided, the hook and loop fastener preferably is used in addition to the mount structure 340. However, in some embodiments, the hook and loop fastener may replace the mount structure 340 entirely.

When provided, the hook and loop fastener includes a first portion attached to the base 100 and a second portion attached to either the mount structure 340 or directly to one or both faces 305, 310 of the blade 300. Preferably, the second portion of the hook and loop fastener is attached to the mount structure 340 on both the first 305 and second 310 faces of the blade 300 so that the blade 300 can be positioned in either the first 315 or second 320 orientation as desired.

As discussed above, it is preferable that the apparatus 10 is configured to be removably attached to a hull of a boat using one or more suction cups 105. In such cases, at least one suction cup 105 on the base 100 forms part of a suction cup assembly 110. Preferably, the suction cup assembly 110 includes at least two (or has exactly two) suction cups 105. However, the suction cup assembly 110 can alternatively include only one suction cup 105, or it can include more than two suction cups 105.

In preferred embodiments, the base 100 further includes a detent 150 having at least first 155 and second 160 positions. In the first position 155, the detent 150 is configured to lock the blade 300 on the base 100. In the second position 160, the detent 150 is configured to release the blade 300 from the base 100. One example of the second position 160 is shown in FIG. 10, and one example of the first position 155 is shown in FIG. 11. Preferably, the detent 150 is rotatable between its first 155 and second 160 positions. However, it should be appreciated that in some embodiments, the detent 150 is not limited to rotational movement, and can instead move linearly, for example. In some embodiments, the detent 150 is part of a suction cup assembly 110 and is located between the base 100 and a suction cup 105.

The illustrated base 100 (e.g., a shoulder thereof) has a channel 165 therein. In a preferred embodiment, the channel 165 is a slot. The illustrated blade 300, and more specifically an adapter component 325 of the illustrated blade, comprises at least one plate, and preferably two plates 355, 365, each configured to be received removably in the channel 165. The adapter component 325 and the channel 165 are shown in FIG. 28. Preferably, the two plates of the adapter component 325 include a first plate 355 disposed adjacent the first face 305 of the blade 300, and a second plate 365 disposed adjacent the second face 310 of the blade 300. The adapter component 325, however, can alternatively have only a single plate, which can be located on either the first face 305 or second face 310 of the blade 300.

The base 100, and more specifically the detent 150, can comprise a body 170 that is moveable between first 175 and second 180 positions. When in the first position 175 (see FIG. 11), the body 170 at least partially closes the channel 165 of the base 100. When in the second position 180 (see (FIG. 10), the body 170 is spaced from the channel 165 of the base 100. In a preferred embodiment, the body 170 comprises a rotatable flange 185 that is rotatable between its first 175 and second 180 positions. However, it should be appreciated that in some embodiments, the body 170 is not limited to rotational movement, and can instead move linearly, for example. The body 170 can optionally comprise a generally circular disc 190 from which the rotatable flange 185 projects. In preferred embodiments, the body 170 is part of a suction cup assembly 110 and the disc 190 is located between a suction cup 105 and the base 100.

When provided, the suction cup assembly 110 can optionally include at least one lever 195 moveable between first 200 and second 205 positions. Preferably, one lever 195 is coupled to each respective suction cup 105 so as to be operable to activate and release suction for the respective suction cup 105. However, it is possible that a single lever could be provided that simultaneously controls the suction force for all or a select group of multiple suction cups. Also, as noted above, there may be only a single suction cup on the apparatus in some cases. When the one or more levers 195 are each in the first position 200 (see, e.g., FIG. 8), each suction cup 105 is in a locked configuration. The locked configuration helps secure the respective suction cup 105 to the hull 40 of the boat 50. When the at least one lever 195 is in the second position 205 (see FIG. 18), the respective suction cup 105 is in an unlocked configuration. The unlocked configuration allows the respective suction cup 105 to be released from the hull 40 of the boat 50. Two levers 195 are each shown in a locked configuration in FIGS. 7, 8 and 19, and in an unlocked configuration in FIG. 18.

In some embodiments, two suction cups 105 are disposed in a confronting angle configuration. In such cases, the confronting angle configuration is characterized by a tilt angle (e.g., relative to horizontal and/or desired plane) of greater than zero degrees and up to three degrees. By having two suction cups 105 in such a confronting angle configuration, the suction cups 105 may adhere particularly stably to a curved surface of a hull 40 of a boat 50.

It is to be appreciated that tool-free adjustment need not be provided in all embodiments of the invention. However, any embodiment of the present disclosure can optionally be provided with tool-free adjustment of the nature described above.

Handle Configuration

In some embodiments, the apparatus 10 has a handle configuration 210 characterized by an aperture 215 in the apparatus 10. Preferably, the aperture 215 is in the base 100, as shown in FIG. 16. The aperture 215 is sized to facilitate manual handling and grasping of the apparatus 10. In a preferred embodiment, the aperture 215 is large enough (e.g., is configured) to receive four fingers of a person's hand. Preferably, the aperture 215 is elongated and/or has a generally rectangular or generally oval shape. However, it is contemplated that the aperture 215 can have any shape as long as it does not interfere with the aperture's intended purpose. In certain embodiments, the aperture has a length of at least two inches, or at least three inches, such as between three inches and six inches.

In a preferred embodiment, the aperture 215 has an aspect ratio of greater than two. As used in the present disclosure, the aspect ratio is defined as a length of the aperture 215 divided by a width of the aperture 215. The length of the aperture 215 is measured along an axis extending between the front end 135 and the rear end 140 of the base 100. The width of the aperture 215 is measured along an axis extending between the first 115 and second 120 side regions of the base 100.

The base 100 preferably has two ribs 230 that extend between (optionally entirely between) the front end 135 and rear end 140 of the base 100. In preferred embodiments, the aperture 215 is located (e.g., defined) between the ribs 230. Preferably, both of the ribs 230 are defined by a single integral body. However, in other embodiments, the ribs 230 can be separate and distinct structures from each other. Each rib 230 preferably is elongated, e.g., so as to have a length longer than six inches, such as between six and 14 inches.

As discussed above, the base 100 has a top side 145 and a bottom side 148. Preferably, the aperture 215 passes entirely through the base 100 from its bottom side 148 to its top side 145. However, in other embodiments, the aperture 215 is a blind opening such that the aperture 215 passes only partially between the bottom side 148 and the top side 145 of the base 100 (e.g., so as to have a closed bottom).

As also discussed above, in some embodiments, the suction cup assembly 110 includes two levers 195, each of which is associated with a respective suction cup 105. Such levers 195 can advantageously be disposed in a recessed area 220 (see FIG. 7) of the base 100. The recessed area 220 can, for example, define a channel 225 that extends between two ribs 230 of the base 100 and is open to aperture 215. Both of the illustrated levers 195 are aligned with the aperture 215 when in their first (locked) positions 200. Preferably, the levers 195 do not hinder (or at least do not prevent) manual access to the aperture 215. Additionally, when in the first position 200, the levers 195 can optionally be located entirely within the recessed area 220, e.g., so that the levers 195 are sheltered from being inadvertently moved to the second position 205 and thus unlocked.

It is to be appreciated that the handle configuration need not be provided in all embodiments of the invention. However, any embodiment of the present disclosure can optionally be so configured.

Lanyard Eyelet

The apparatus 10 preferably has a lanyard eyelet 235. In such cases, in order to tie the apparatus 10 to a boat 50, a tether 500 can be removably attached to both the boat 50 and the lanyard eyelet 235. The tether 500 can comprise a rope, bungee cord or the like.

When provided, the lanyard eyelet 235 preferably is movable between at least first 240 and second 245 positions. When in the first position 240, the lanyard eyelet 235 is located at the first side region 125 of the apparatus 10. When in the second position 245, the lanyard eyelet 235 is located at the second side region 130 of the apparatus 10. FIG. 14 shows the lanyard eyelet 235 in the first position 240, and FIG. 15 shows the lanyard eyelet 235 in the second position 245. Providing for such movement of the lanyard eyelet 235 is advantageous since it can be positioned as needed for convenient attachment thereto by a tether 500. For example, when the front end 135 of the base 100 faces rearwardly of the boat 50, the lanyard eyelet 235 can be moved to the first position 240, and thus, to the first side region 125 of the base 100. On the other hand, when the rear end 140 of the base 100 faces rearwardly of the boat 50, the lanyard eyelet 235 can be moved to the second position 245, and thus, to the second side region 130 of the base 100. This may make it possible to use a shorter length of tether, which may be advantageous. It can also help keep the tether up out of the water flow path along the wake shaping apparatus.

Preferably, the apparatus 10 includes a suction cup assembly 110 comprising a disc 250 that is rotatable between first 240 and second 245 positions (see FIGS. 14 and 15). In preferred embodiments of this nature, the lanyard eyelet 235 can optionally be part of the suction cup assembly 110 and may be located between a suction cup 105 and the base 100. In such cases, the lanyard eyelet 235 preferably is a projection of the rotatable disc 250.

In another embodiment, the suction cup assembly 10 does not include rotatable disc 250. In this embodiment, the lanyard eyelet 235 can be fixedly or removably attached to any portion of the apparatus 10.

In embodiments where the apparatus 10 includes a suction cup assembly 110 having two suction cups 105, the rotatable disc 250 and a generally circular disc 190 can each be positioned in a stacked orientation and located between a respective suction cup 105 and the base 100. Alternatively, in another embodiment having only a single suction cup 105, rotatable disc 250 can be omitted, while a generally circular disc 190 is positioned between the single suction cup 105 and the base 100.

A detailed view of one example of a suction cup assembly 110 is shown in FIG. 17. Here, each lever 195 of the suction cup assembly 110 has a hole 505 disposed therein. A pin 510 is provided for each lever 195 such that one of the pins 510 can be received in the hole 505 of the respective lever 195. Each suction cup 105 further has a post 515 attached thereto and extending outwardly therefrom. Each post 515 has a hole 520 disposed therein. In addition to passing through the hole 505 of the respective lever 195, each pin 510 also passes through the hole 520 of the post 515 of the respective suction cup 105. Additional holes (not shown) are provided in the base 100, disc 190, and disc 250 to allow the levers 195 to attach to the respective suction cups 105. The suction cup assembly 110 also includes springs 525, optionally such that one spring 525 is provided for each lever 195. The springs 525 are located between the levers 195 and their respective suction cups 105.

It is to be appreciated that the lanyard eyelet need not be provided in all embodiments of the invention. However, any embodiment of the present disclosure can optionally be provided with an adjustable lanyard eyelet of the nature described above.

Mount Structure

As discussed above, the apparatus 10 preferably has different configurations depending on whether the base 100 is mounted to the blade 300 (first configuration 20) or separated from the blade 300 (second configuration 30). Additionally, when the apparatus 10 is in the first configuration 20, the blade 300 preferably is in either a first orientation or a second orientation, depending on which face 305, 310 of the blade 300 faces the desired direction relative to the base 100.

As also discussed above, the blade 300 can advantageously be equipped with a mount structure 340 that projects outwardly from at least one, and preferably both, faces 305, 310 of the blade 300. In some embodiments, the mount structure 340 comprises a first detent 345 that projects from the first face 305 of the blade 300, and a second detent 350 that projects from the second face 310 of the blade 300. The first detent 345 is configured to attach to the base 100 of the apparatus 10 such that the blade 300 is retained in the first orientation 315. The second detent 350 is configured to attach to the base 100 of the apparatus 10 such that the blade 300 is retained in the second orientation 320.

In certain embodiments, the first 345 and second 350 detents are fixed in place on (i.e., so as not to be movable relative to) the blade 300. In other embodiments, however, the first 345 and second 350 detents are part of an adapter component 325 that is moveable (e.g., relative to a primary wall of the blade 300) between at least first 330 second 335 positions. In the first position 330, the adapter component 325 is configured to attach to the base 100 of the apparatus 10 such that the blade 300 is retained in the first orientation 315. In the second position 335, the adapter component 325 is configured to attach to the base 100 of the apparatus 10 such that the blade 300 is retained in the second orientation 320.

In some embodiments, the blade 300 is configured to lie at least generally in a plane (e.g., has a configuration that is at least generally planar), and the adapter component 325 is configured to move at least generally perpendicular to such plane when the adapter component 325 moves between its first 330 and second 335 positions. The adapter component 325 can also move to an intermediate position 338 that is in-between the first 330 and second 335 positions. The first 345 and second 350 detents can optionally be connected together by conventional fasteners, such as nuts and bolts. Such fasteners can allow the first 345 and second 350 detents to slide between the first 330 and second 335 positions.

As shown in FIG. 29, when the adapter component 325 is in the first position 330, the first detent 345 projects further from the first face 305 of the blade 300 than it does when the adapter component 325 is in the second position 335. Likewise, when the adapter component 325 is in the second position 335, the second detent 350 projects further from the second face 310 of the blade 300 than it does when the adapter component 325 is in the first position 330. FIG. 29 shows the adapter component 325 in the first position 330 (image on the left), the second position 335 (middle image), and the intermediate position 338 (image on the right).

The first detent 345 of the adapter component 325 can optionally comprise a first plate 355 having a first mounting flange 360. Similarly, the second detent 350 of the adapter component 325 can optionally comprise a second plate 365 having a second mounting flange 370. Preferably, the first 355 and second 365 plates are moveable conjointly relative to the first 305 and second 310 faces of the blade 300. When the blade 300 is positioned in the first orientation 315, the first mounting flange 360 is received in the channel 165. When the blade 300 is positioned in the second orientation 320, the second mounting flange 370 is received in the channel 165.

As discussed above, the base 100 has opposed first 115 and second 120 end regions. The first end region 115 (e.g., a shoulder 255 thereof) defines the channel 165. In a preferred embodiment, the first end region 115 has a greater height than the second end region 120. Alternatively, in some embodiments, the first and second end regions can be identical in height, or the second end region can have a taller height than the first end region so long as the second end region includes the channel.

It is to be appreciated that the preferred blade mount structure need not be provided in all embodiments of the invention. However, any embodiment of the present disclosure can optionally be provided with a blade mount structure of the nature described above.

Adjustable Base

In certain embodiments, the base 100 is an adjustable base 100 a. In some embodiments of this nature, the first end region 115 of the adjustable base 100 a has a first suction cup 105 a, and the second end region 120 of the adjustable base 100 a has a second suction cup 105 b. To make such a base adjustable, the first end region 115 can optionally have a pivot connection 260 with the second end region 120. In some cases, the pivot connection 260 allows the suction cups 105 a, 105 b to be oriented at various angles relative to each other. In this manner, the pivot connection 260 may permit the suction cups 105 a, 105 b to be stably mounted to surfaces of different contours, including both flat and curved surfaces. For example, the suction cups 105 a, 105 b may be configured to be positioned in a confronting angle configuration such that the suction cups 105 a, 105 b are angled somewhat inwardly toward each other.

When provided, the pivot connection 260 preferably comprises a first pivot joint having a first pivot axis. In FIG. 20, the first pivot joint enables adjusting an angular orientation of the second end region 120 relative to that of the first end region 115 such that the apparatus 10 has at least first and second angular configurations. The first angular configuration is characterized by the first and second end regions extending along a straight line (see FIG. 19). The second angular configuration is characterized by one of the first 115 and second 120 end regions projecting away from the other at a positive acute angle (see FIG. 20). In this embodiment, both the first 105 a and second 105 b suction cups can remain in a constant plane while the apparatus 10 is moved between its first and second angular configurations.

Referring now to FIG. 21, the pivot connection 260 can optionally comprise a second pivot joint having a second pivot axis. In other embodiments, the pivot connection 260 includes both the first and second pivot joints. In FIG. 21, the pivot connection has only the second pivot joint. The second pivot joint enables pivoting the apparatus 10 in either a first direction or a second direction. In particular, when the apparatus 10 is pivoted in the first direction, the first 105 a and second 105 b suction cups pivot toward each other. When the apparatus 10 is pivoted in the second direction, the first 105 a and second 105 b suction cups pivot away from each other.

The pivot connection 260 can optionally comprise a ball joint, as shown in FIG. 22. When provided, the ball joint preferably is located between the first 115 and second 120 end regions of the adjustable base 100 a and preferably is configured to enable pivotal movement between the first 115 and second 120 end regions.

It is to be appreciated that the adjustable base structure need not be provided in all embodiments of the invention. However, any embodiment of the present disclosure can optionally be provided with an adjustable base structure of the nature described above.

Splash Deflector

The invention also provides embodiments wherein a splash deflector 265 is mounted removably and non-invasively to a boat 50. The splash deflector 265 is intended to limit the splash of water adjacent to a region of the boat 50 where the splash deflector 265 is attached. The illustrated boat 50 has a transom 60 that extends between opposed sides 70, 80 of the hull 40. The splash deflector 265 can be mounted to the transom 60, as shown in FIG. 27, or to a desired one of the sides 70, 80 of the hull 40, as shown in FIGS. 23 and 26.

If desired, first and second splash deflectors can be mounted respectively on first and second sides of the hull. Additionally or alternatively, first and second splash deflectors can be mounted on the transom of a boat. Given the present teaching as a guide, skilled artisans will appreciate that one or more splash deflectors can be provided at various locations on one or both sides of the hull and/or at various locations on the transom.

The splash deflector 265 comprises both a splash wall 270 and a mount wall 275. The splash wall 270 is attached to and projects outwardly from the mount wall 275. When the splash deflector 265 is attached to the hull 40 of a boat 50, the mount wall 275 is carried alongside the hull 40, and the splash wall 270 projects away from the hull 40. As shown in FIG. 26, the splash wall 270 can be planar, or at least generally planar, such that it extends away from the mount wall 275 in a generally perpendicular manner. Alternatively, as shown in FIGS. 23 and 27, the splash wall 270 can be arcuate, e.g., so as to form a curved fender configuration.

The splash deflector 265 is removably mounted to a boat 50, preferably by one or more suction cups 280. In a preferred embodiment, the mount wall 275 of the splash deflector 265 includes two suction cups 280, as shown in FIG. 25. However, in other embodiments, the splash deflector 280 has only a single suction cup 280, or it has more than two suction cups 280. Moreover, instead of suction cups 280, the splash deflector 265 can be attached to the boat by other non-invasive and removable forms of mechanical attachment, such as hook and loop fasteners, magnets or the like.

Similar to the wake shaping apparatus 10, the splash deflector 265 can optionally include one or more levers 285 that control suction of the preferred suction cups 280. Preferably, one lever 285 is provided for each suction cup 280, as shown in FIG. 24. However, a single lever could alternatively be provided that controls suction for all suction cups on the mount wall. The lever 285 can be moved between a locked configuration and an unlocked configuration. In the locked configuration, each lever 285 activates suction for the respective suction cup 280. In the unlocked configuration, each lever 285 releases suction for the respective suction cup 280.

Preferably, the splash deflector 265 has an aperture 290 passing therethrough. When provided, the aperture 290 preferably is sized to facilitate manual handling and grasping of the splash deflector 265. In such cases, the aperture 290 is configured to receive four fingers of a person's hand. The mount wall 275 has a first surface 295 and a second surface 298. Preferably, the aperture 290 passes entirely through the mount wall 275 from its first surface 295 to its second surface 298, as shown in FIG. 23. In other embodiments, however, the aperture comprises a blind bore such that the aperture passes only partially between the first surface and the second surface of the mount wall

The splash deflector 265 can be used with or without the wake shaping apparatus 10. When the splash deflector 265 and the wake shaping apparatus 10 are used in combination, the splash deflector 265 is positioned above the apparatus 10, as shown in FIG. 27. Such positioning of the splash deflector 265 can advantageously limit the amount of water from the apparatus 10 that splashes into the boat 50.

In certain embodiments, the splash deflector and the wake shaping apparatus are two discrete components that can be removably attached to each other during use. Removable attachment of the splash deflector and the wake shaping apparatus can be accomplished by various conventional means, including, but not limited to, a mounting wall (not shown) attached to both the splash deflector and the apparatus by screws or other fasteners.

In other embodiments, the splash deflector and the apparatus are integrally formed such that they define a one-piece structure. For example, a mounting wall can be provided that fixedly attaches the splash deflector to the wake shaping apparatus.

Adjustable Blade

In some embodiments, an angular orientation of the blade 300 (e.g., relative to the base 100) can be adjusted. This feature allows the blade 300 to be adjusted so as to project away from the base 100 at different angles to provide various effects on the wake. In the present embodiments, the blade 300 has at least first and second orientations. In the first orientation, the blade 300 projects away from the base 100 at a first angle. In the second orientation, the blade 300 projects away from the base 300 at a second angle. The first and second angles are different. Preferably, the blade 300 is pivotable between the first and second orientations via a hinge 380. The hinge 380 can be a simple hinge, as shown in FIG. 30, or a virtual hinge, as shown in FIG. 31.

The blade 300 further includes a mounting plate 385. The mounting plate 385 is attached to the blade 300 (e.g., is attached to a primary wall portion of the blade), e.g., via the hinge 380, preferably such that the hinge 380 enables the blade 300 (or a primary wall portion thereof) to pivot relative to the mounting plate 385. Similar to the first 355 and second 360 plates described above, the mounting plate 385 can be removably mounted in a channel 165 defined by the base 100. In some embodiments, the mounting plate 385 is attached directly to the blade 300 (e.g., to a primary wall portion thereof) via the hinge 380.

As shown in FIG. 30, an optional base plate 390 can be provided. The base plate 390, for example, can be attached to the blade 300 (e.g., to a primary wall portion thereof) between the blade 300 (e.g., a primary wall portion thereof) and the mounting plate 385. In FIG. 30, the mounting plate 385 is hingedly attached to the base plate 390 such that the mounting plate 385 is pivotable relative to the base plate 390.

As discussed above, FIG. 31 shows a virtual hinge allowing the blade 300 to pivot between the at least first and second orientations. In some embodiments having a virtual hinge, the mounting plate 385 has a projection 395 extending outwardly therefrom. The projection 395 of the mounting plate 385 can have a slot 398 disposed therein. Preferably, the projection 395 is a semi-circle, and/or the slot 398 is arcuate, as shown in FIG. 31. However, other shapes for both the projection 395 and the slot 398 are contemplated.

In a preferred embodiment, a knob and bolt structure is provided. In certain embodiments, two walls (not shown) are attached to and extend between the blade 300 and the mounting plate 385. One or more bolts can be attached to the walls. One or two knobs can be provided, and each knob is attached to an end of the respective bolt. The bolt(s) are received in the slot 398 and are movable along a length of the slot 398. Tightening of the bolts permits the mounting plate 385 and the blade 300 to be locked at a desired angle relative to each other.

Blade with Channels

Referring to FIGS. 32 and 33, in certain embodiments the blade 300 has a plurality of channels 400. The channels 400 preferably are integral to the blade 300 in that the blade 300 defines walls 405 bounding the channels 400. When the blade 300 is attached to the base 100, the channels 400 (or at least some of the channels) on the blade 300 preferably extend generally away from the base 100.

The channels 400 have a configuration designed to impact water flow along the blade. For example, the shape, size and orientation of the channels 400 may affect the shape of the wake. The channels 400 can be provided on either or both faces 305, 310 of the blade 300. The channels 400 can have different configurations on each face 305, 310 in order to provide different effects depending upon which face 305, 310 of the blade 300 faces the base 100.

The channels 400 on a single blade 300 can all be uniform in size. Alternatively, the channels 400 on the blade 300 can be different in size. Where the channels 400 on the blade 300 are uniformly sized, the channels 400 can all be customized so they are smaller or larger as desired to affect performance.

Additionally, the walls defining the channels 400 can optionally project outwardly from the blade 300 at a 90-degree angle, or they can form any angle with the blade 300 that is greater than zero. In certain embodiments, all the channels 400 on a given side of the blade are uniform in orientation and size. Alternatively, in some embodiments, the orientations of certain channels 400 on the blade 300 and/or the sizes of certain channels 400 are not uniform. Certain embodiments provide one side of the blade with channels of a given configuration, while channels on the other side of the blade have a different configuration.

In FIGS. 32 and 33, all of the channels 400 are at least generally parallel to one other. Thus, the channels 400 can optionally be parallel to one another along an entire lengthwise extent of the blade 300. Although the channels 400 are shown as extending in straight lines across the blade 300, at least some (or all) of the channels 400 may instead be curved, e.g., one or more of them may have curved portions.

The illustrated blade 300 further includes a mount region 410 configured to be carried against the base 100. The mount region 410 preferably is devoid of channels 400 so as not to interfere with mounting the blade 300 to the base 100. Depending on the particular embodiment, the mount region 410 can be an area on the blade 300 where an optional adapter component 325, mount structure 340, mounting plate 385, and/or base plate 390 are disposed.

Deployable Lanyard Assembly

In some embodiments, the invention provides a lanyard assembly 530. Referring to FIGS. 34-37, one example of the lanyard assembly 530 comprises a tether portion 535 and a float portion 540. The tether portion 535 comprises a tether line 555 configured for attaching to a cleat 560 on a boat 50. The tether line 555 can comprise a rope, bungee cord or the like. The float portion 540 comprises both a float 545 and a float line 550. The float line 550 can comprise a rope, bungee cord or the like and is configured for attaching to the base 100 of the apparatus 10. In some cases, the float line 550 can be attached to a lanyard eyelet 235 of the base 100.

Preferably, the tether portion 535 and the float portion 540 are configured to be connected (and in FIG. 34, are connected) to each other by a friction joint. For example, the tether portion 535 can optionally comprise a male detent (e.g., a tongue) 565 and the float portion 540 can comprise a female detent 570. Alternatively, the male detent can be provided on the float portion while the female portion is provided on the tether position. In such cases, the male 565 and female 570 detents collectively define the friction joint. Various other friction joint structures can alternatively be used.

The tether line 555 has first 575 and second 580 ends. The first end 575 of the tether line 555 is configured to be attached to a cleat 560 on a boat 50. The second end 580 of the tether line 555 can optionally have a tongue 585. The float line 550 also has first 590 and second 595 ends. The first end 590 of the float line 550 is configured to be attached to the float 545. The second end 595 of the float line 550 is configured to be attached to the base 100. For example, in some cases the second end of the float line 550 is configured to be attached to a lanyard eyelet 235 of a wake shaping apparatus 10. The float 545 has front 600 and rear 605 ends. In the embodiment illustrated, the rear end 605 of the float 545 has an opening 610. The second end 595 of the illustrated float line 550 also has an opening 615. The tongue 585 of the tether line 555 can be received in both openings 610, 615 so as to provide a friction fit therebetween.

The float 545 is buoyant such that it is configured to float on water. In a preferred embodiment, the float 645 is a foam material (e.g., a closed foam). However, the float 645 can comprise virtually any buoyant material, e.g., an inflatable plastic, so long as the float 545 is capable of providing buoyancy in water. As shown in FIGS. 36 and 37, the float 545 has a bore (e.g., an axial bore) 630 extending between the front 600 and rear 605 ends thereof. Here, the tether line 555 extends through the bore 630 of the float 545.

Inflatable Wake Shaper Apparatus

In certain embodiments, the invention provides a wake shaping apparatus 10 that is an inflatable apparatus 10 b. In such cases, the apparatus (at least when inflated) preferably can float on water. As used in the present disclosure, the term “inflatable apparatus” refers to an apparatus that can transition between a non-inflated state and an inflated state. The means for inflating the inflatable apparatus 10 b can be air or other gas, water or other liquid, or a combination of gas and liquid. In some cases, the apparatus 10 b is configured to have a varied internal pressure of gas or liquid (i.e., it can be inflated to different extents) to create multiple but intentional effects, such as different shapes and/or angles of the apparatus 10 b.

Referring to FIGS. 38 and 39, the inflatable apparatus 10 b has a plurality of walls 615. In some embodiments, none of the walls 615 are rigid. In other embodiments, one or more of the walls 615 are rigid to help define a shape of the apparatus 10 b. For example, while being inflated, the apparatus 10 b can optionally expand until one of the rigid walls forms a desired angle with an adjacent non-rigid wall. The extent of expansion, and thus, the angle the rigid wall forms with the adjacent non-rigid wall, can optionally depend on a volume of gas and/or liquid introduced into the apparatus 10 b. Where the apparatus 10 b includes multiple rigid walls, the apparatus 10 b can be inflated to different extents such that the walls form different angles relative to each other. For instance, each rigid wall can form a unique, desired angle with an adjacent non-rigid wall. FIGS. 38 and 39 also show that the apparatus 10 b can in some cases be completely or substantially flattened when fully deflated, e.g., to permit compact storage of the apparatus 10 b.

In some embodiments, the apparatus 10 b is empty and void of any internal structure. In other embodiments, the apparatus 10 b has inner chambers to provide rigidity, provide ballast and/or help define an inflated shape of the apparatus 10 b. Additionally, the apparatus 10 b can include internal structural elements that are independent of gas or liquid. Such internal structure could include drop stitch technology, in which tethers, such as strings or ropes, are attached to two or more walls 615 that define the shape of the apparatus 10 b. These tethers can optionally be flexible in a non-pressurized compressed environment. However, when the apparatus 10 b is inflated, the tethers may become taut and prevent the walls 615 from extending beyond an intentional length, thus confining the apparatus 10 b to a desired pressurized shape.

As shown in FIG. 40, the apparatus 10 b is used in combination with a boat 50 and can be attached to various locations on the boat 50. For example, the apparatus 10 b can be attached to a single side 70, 80 of the hull 40. Alternatively, two inflatable apparatuses 10 b can be used such that one apparatus 10 b is attached to one side 70 of the hull 40 while another apparatus 10 b is attached to the other side 80 of the hull 40. Each apparatus 10 b can be permanently or removably attached to the boat 50. Preferably, the apparatus 10 b is attached to the boat 50 by at least one, and preferably two, suction cups 620. This, however, is by no means required. It is also contemplated that the apparatus 10 b can include only a single suction cup 620, or more than two suction cups 620. Alternatively, other removable and non-invasive forms of mechanical attachment, such as magnets, hook and loop fasteners or the like, can be provided for securing the apparatus 10 b to the hull 40 of a boat 50.

Where two inflatable apparatuses 10 b are used on a boat 50, each apparatus 10 b can have an independent source (or a common source) of gas and/or liquid as the means for inflation. As shown in FIG. 40, this source can include a controller 625 to regulate a volume of gas and/or liquid distributed into each apparatus 10 b by increasing or decreasing the pressure of the gas and/or liquid. These pressure changes can occur with the use of conventional valves in either an open or contained system. Such a system could have one or more gas or liquid pumps to operate the system to achieve desired levels. The system could also be an intake and dump-type siphon system, in which movement of the boat 50 is used as a means of intake to pressurize the system. Deflating or dumping pressure can be accomplished, for example, by pump or generator, natural aspiration allowing pressure inside the source container to equalize naturally, and/or with the assistance of motion of the boat 50 and force inflicted on the outside of the source containers.

Such a system, as described above, would allow switching from operation of one inflatable apparatus 10 b on one side 70 of the hull 40 to operation of the other apparatus 10 b on the opposite side 80 of the hull 40 as needed. Thus, a selected one or more of the inflatable apparatuses 10 b can be inflated, or all of the inflatable apparatuses 10 b can remain in their uninflated states. Advantageously, this system creates the desired effect of either virtually elongating one side 70, 80 of the hull 40 or intentionally destroying wake development on one side of the boat 50. Both effects can be used to generate mismatched wake conversion, and therefore, larger wake development for one side of the boat 50 relative to the other side of the boat 50.

In certain embodiments, the inflatable apparatus 10 b has at least one wall 615 that is concave. In the embodiment of FIGS. 41 and 42, for example, a wall 615 (e.g., a top or leading wall) is concave so as to bound a channel 615C. Configurations of this nature may provide special wake effects, e.g., by virtue of creating a somewhat channeled flow, which may have particular flow characteristics, such as laminar or substantially laminar flow through the channel. When the inflatable apparatus 10 b is mounted operatively to the hull of a boat, the wall 615 bounding the channel 615C may face generally away from the hull and/or it may be oriented at an angle α (as measured relative to an axis normal to the hull surface to which the apparatus is attached and/or relative to a bottom wall 615 of the apparatus). The angle α convention here is best appreciated with reference to FIG. 39.

As shown in FIG. 39, the inflatable apparatus 10 b can optionally include a leading wall 615 and a trailing wall 615 that are oriented at different angles α, θ. In some cases, angle α may be greater than 45 degrees, while angle θ is less than 45 degrees.

The inflatable apparatus 10 b preferably has a wall 615 (e.g., a bottom wall) to which one or more (e.g., a plurality of) suction cups 620 are attached. In some cases, the one or more suction cups 620 are joined to a bottom wall 615 of the inflatable apparatus 10 by ultrasonic welding. In such cases, the suction cups are not intended to be separated from the bottom wall of the apparatus, but rather are integral/permanently attached to the bottom wall.

In some embodiments, the inflatable apparatus 10 b includes a first wall 615 (e.g., a leading or front wall) that is rigid, a second wall 615 (e.g., a bottom wall) that is rigid, and one or more walls (e.g., side walls) 615 that are flexible. The one or more flexible walls may form (or be part of) a flexible, inflatable/collapsible enclosure, such as a PVC bag or another flexible bag or other bellows. The second wall 615 may be a bottom wall, and one or more suction cups may be attached to the bottom wall. Furthermore, if an apparatus of this nature has a channel 615C, then the first wall 615 can optionally bound the channel.

In embodiments where the wake shaping apparatus 10 is an inflatable apparatus 10 b, one or more of the walls 615 may be rigid. As just one example, such a rigid wall may comprise flexible top and bottom layers (e.g., comprising PVC or another polymer) between which there is sandwiched a rigid sheet (e.g., comprising ABS or another rigid plastic).

FIG. 43 shows another embodiment involving an inflatable apparatus 10 b. Here, the wake shaping apparatus 10 comprises a base 10 bp that can be removably secured to the hull 40 of a boat, and an inflatable apparatus 10 b that can be removably secured to the base 10 pb. The inflatable apparatus 10 b may be removably secured to the base 10 bp by virtue of, for example, the bottom wall 615 of the inflatable apparatus 10 b having two slots respectively configured to releasably receive and retain the two levers 195. Additionally or alternatively, there can be another releasable mechanical attachment, such as hook and loop fasteners, clasps, magnets, or the like.

As shown in FIG. 43, the base 10 bp preferably includes one or more (preferably a plurality of) suctions cups 620. In the embodiment illustrated, each suction cup 620 is operably coupled with a lever 195, which can optionally be of the nature described elsewhere in this disclosure. Instead of levers, the suction cups can have other actuators, or may simply be configured to be pressed onto the hull without having actuators. Furthermore, instead of suction cups, the base can be removably attached to the hull through other non-invasive forms of mechanical attachment, such as hook and loop fasteners, clasps, magnets, or the like. Moreover, in some cases, the base 10 bp can have a different configuration so as to be attached permanently to the hull.

In certain embodiments, the inflatable apparatus 10 b includes a wall 615 that is a leading (or “front”) wall, and thus faces generally way from the bottom of the apparatus and/or away from the hull 40. If desired, this leading (or “front”) wall 615 can be a rigid wall having a flange 615F projecting rearwardly of a rear wall (which may be a flexible, collapsible/expandable rear wall) of the inflatable apparatus. Reference is made to FIG. 43. While this figure involves a separable base 10 bp, it is to be appreciated that a rearwardly projecting flange 615F can optionally be provided on an embodiment like the one shown in FIGS. 41 and 42, or on various other inflatable embodiments where there is no separable base.

In some embodiments, the inflatable apparatus 10 b has one or more apertures 615H formed so as to extend into the apparatus. Reference is made to FIGS. 44A-44C. Here, one or more apertures 615H pass entirely from (and through) one wall 615 (optionally a sidewall) of the inflatable apparatus 10 b to (and through) another wall 615 (optionally an opposed sidewall) of the apparatus 10 b. In other cases, the apertures may be formed as blind bores. The aperture(s) 615H preferably are exposed/open through one or more walls 615 of the inflatable apparatus 10 b. In some cases, each aperture 615H opens through two walls 615 of the inflatable apparatus 10 b. When provided, the aperture(s) 615H are configured to reduce buoyancy of the inflatable apparatus 10 b. This can make it easier to push under water, such as when mounting onto the hull 40 of a boat. Although not shown in FIGS. 44A-44C, there preferably are one or more suction cups or other mechanical attachments on the bottom of the inflatable apparatus in these embodiments.
